Description

[Detailed Description of the Invention] The present invention relates to a chamfered accessory tile used for the protruding corners.

The conventional construction of tiles at the protruding corners is as shown in Fig. 1.
By using rounded corners, aesthetics and safety for the human body were ensured. In this case, the accessory tile 1 can be used either to the left or right of the protruding corner 2, so whether the accessory tile 1 is used to the left or right of the protruding corner 2 depends on the construction. It was left to the discretion of the business operator. For this reason, during construction, the contractor himself was sometimes confused about which direction to use.

Further, as shown in FIG. 2, when the protruding corner part 2 has a shelf shape, when the accessory tile 1 is used on the left side of the protruding corner part 2, the vertical joints 4 between the regular tiles 3 on the right side, Accessory tile 1 with double-sided bevel on shelf 5
2 and the joints 6 formed between the single-sided accessory tiles 13 were sometimes uneven. For this reason, it was necessary to cut the tiles 3' arranged in the first column on the right side of the projecting corner 2, as shown in FIGS. 3 and 4, before use. That is, when viewed from above, if the length of one side of the square accessory tile 1 and the regular tile 3 is L, the thickness is _t1 , and the joint width is _t2 , the length of the cut tile 3' is: L-(t ₁ +t ₂ ), and it was necessary to cut the regular tile 3 to this length. For this reason, conventionally, when forming the shelf-shaped protruding corner portion 2, a lot of effort was required. Further, the cut surfaces of the cut tiles 3' are not smooth and the dimensional accuracy of the cut surfaces is poor, resulting in a disadvantage that the aesthetic appearance is impaired. These things are the same when forming the protruding corner portion 2 and the floor surface. In view of the above-mentioned drawbacks of the conventional technology, the present invention has been developed to improve and eliminate them, and is to cut a part of the rounded surface of the chamfered accessory tile in a 45-degree direction from the back side of the tile to form a joint formation surface. The present invention aims to provide an accessory tile in which a protruding corner can be formed without cutting an ordinary tile.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings. Note that members having the same symbols as in the conventional case are the same members.

FIG. 5 shows the accessory tile 7 according to the present invention. As shown in the figure, this tile 7 is
It has a rounded surface portion 8 formed from the tile surface 7a to one tile side surface 7b. Then, a joint forming surface 9 is provided by cutting a part of this rounded surface portion 8 in a 45 degree direction from the tile back surface 7c side. In this case, the joint forming surface 9 and the tile back surface 7c
The angle it makes with is 135 degrees. The optimum embodiment of the rounded surface portion 8 and the joint forming surface 9 is as shown in FIGS. 6 and 7. That is, the rounded surface portion 8 may have a curvature whose radius is the thickness t ₁ of the accessory tile 7. This is because when the protruding corner portion 2 is formed, the rounded surface portions 8, 8 of the accessory tiles 7, 7 on both sides exhibit the same continuous curvature, which improves the external appearance (No. (See Figure 7). On the other hand, in order to provide the joint forming surface 9, P is first inserted into the tile back surface c by a distance corresponding to the tile thickness _t1 from the edge 10 where the rounded surface portion 8 and the tile back surface 7c intersect. 7, pass through this P and
Draw an imaginary line a at 45 degrees from the c side toward the R surface portion 8. Then, the R surface portion 8 of the accessory tile 7 may be cut so as to be parallel to the temporary line a at a distance of half the joint width t ₂ from this line a. With this configuration, the accessory tile 7 can be used on either the left or right side of the protruding corner portion 2, which is convenient for construction work. That is, there is no need to separately manufacture accessory tiles 7 arranged on the left and right sides of the protruding corner portion 2. Moreover, if the protruding corner part 2 is formed with such an accessory tile 7, as shown in FIG.
The joint portions 11 are located at the corners of the curved surfaces, resulting in an aesthetically pleasing product. In addition, since the corners are curved, there is no risk of injury even if a human body comes into contact with it, making it safe.

Furthermore, after pasting to the protruding corner portion 2, the end portion 7d of the accessory tile 7 facing the R surface portion 8 is connected to the accessory tiles 12, 13 and the normal tile 3 from one end surface of the protruding corner portion 2. It is located at a distance of one side length L. Therefore, even when this accessory tile 7 is applied to the protruding corner part 2 where the shelf part 5 is formed, as shown in FIG. 8, the shelf part 5 and the protruding corner part 2 are formed. The joints between the standing wall surface and the floor surface will not be uneven. Therefore, there is no need for troublesome work such as cutting the tiles arranged on one side of the protruding corner portion 2, as in the conventional case.

Note that the accessory tile of the present invention is not limited to the single-sided one described above, but can also be applied to double-sided accessory tiles, single-sided corner tiles for inner baseboards, and the like.

As explained above, in the present invention, a part of the rounded surface of the chamfered accessory tile is cut in a 45-degree direction from the back side of the tile to provide a joint forming surface. When forming tiles, there is no need to cut and use ordinary tiles, and the work is simple. Moreover, since it can be used for both the left and right sides of the projecting corner, there is no need to manufacture the left and right sides separately, resulting in high productivity. Furthermore, since the joint portion of the protruding corner portion is located at the corner portion, the appearance is good. Furthermore, since the curved protruding corner portion is obtained, even if a human body comes into contact with it, there is no risk of injury, and it is extremely safe.
